2. Figure 1
Transverse ultrasound image of the right lower quadrant shows poorly marginated hypoechoic/cystic tender abnormality (A) consistent with a small abscess. Note the linear echogenic object within the collection, in keeping with toothpick (double thin arrows) with a portion of it (single arrow) extending beyond the confines of the abscess cavity. R = rectus muscle; C = cecum.

3. Figure 2
Non-enhanced CT image of the right iliac fossa shows hyperdense toothpick (arrows) seen perforating through the medial wall of the cecum (C). Note the inflammatory stranding (A) in the pericecal fat surrounding the toothpick. IP = iliopsoas; R = rectus muscle.

4. Figure 3
Enhanced transverse CT image, same level as figure 2, again demonstrates pericecal inflammation. Toothpick (arrows) is not as clearly discernible as on non enhanced image in Figure 2, due to enhancing phlegmonous inflammation around it (A). IP = iliopsoas; R = rectus muscle; C = cecum.
